5 Claims.

This invention relates to new and useful improvements in well pumping equipment.

This application is filed as a divisional application of my original co-pen-ding application filed December 15, 1933, Serial No. 702,548.

One object of the invention is to provide pumping equipment wherein an improved swing is employed for transmitting motion from a pumping power to a rod line.

An important object of the invention is to provide an improved swing beam for transmitting motion from a pumping power to a rod line which is arranged so as to reduce rod line vibration to a minimum, and which is so constructed that transmission ratios may be set up for controlling the length of the stroke or travel of the rod line.

Another object of the invention is to provide an improved swing beam wherein the supporting bearing, as well as the bearings to which the pitman and rod line are connected are constructed so as to insure constant lubrication and to withstand heavy loads, as well as being substantially dust and water proof.

A further object of the invention is to provide an improved swing which is capable of pumping two wells at the same time and which is so designed that the well to be pumped or operated can be located at most any angle with relation to the pumping power, thereby making it unnecessary for said well to be in direct line with said power.

Still another object of the invention is to provide an improved swing which is adapted to be connected with the usual pitman of a pumping power and operated by a push and pull motion, the swing having means whereby a suitable knock-off or disconnecting device may be connected therewith.

A construction designed to carry out the invention will be hereinafter described, together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Figure l is a plan view of a swing beam constructed in accordance with the invention,

Figure 2 is a side elevation of the same,

Figure 3 is a vertical, sectional view of the swing bearing and support, and taken on the line 33 of Figure 1,

Figure 4 is a transverse, vertical, sectional view taken on the line 4-4 of Figure 1,

Figure 5 is a vertical, sectional view, taken on the line 5-5 of Figure 4,

Figure 6 is a plan view (details omitted) showing the swing connected with a pumping power and rod line,

Figure 7 is a view, partly in section and partly in elevation of a modified form of the swing, and

Figure 8 is a transverse, vertical sectional View, taken on the line 88 of Figure 7.

In the drawings, the numeral ll] designates a pumping power (Figure 6) which may be of any suitable type. The usualpitman II has one end pivoted to the eccentric ring [2 of said power. It is customary to provide a shelf or rail l3 on which the pitman may rest when it is disconnected from the swing. The loop M at the other end of the pitman is connected to a hook 15 carried by a swing beam l6 which is mounted to swing on a post ll.

The hook I5 is attached to a bearing collar l8 mounted in the beam (Figures 1, 4 and 5) A second bearing collar l9 also mounted in the beam is H connected through a suitable knock-oil or disconnecting device 20 with a rod line 2|. The rod line has connection with the usual pump jack (not shown). The pump rods in the well exert a pull on the rod line H which pull is applied to the parts attached thereto and transmitted back to the power [0. With the hook-off 2!] connecting the rod line with the swing, the pull exerted by the power l0 through the pitman is transmitted to the rod line. gaged, themotion from the pumping power will not be transmitted to the rod line 2!. It is noted that the pumping power and hook-off device 20 form no part of the present invention, the latter being fully described in our co-pending application filed December 15, 1933, Serial No. 702,548. In fact it would be possible to eliminate the hookoff entirely and connect the rod line 2| directly to the bearing IS.

The swing beam i6 is formed of top and bottom channels 22 and 23, the upper one being inverted so that their flanges are inwardly opposed and spaced apart. These channels are provided with bolt holes 24 and 25. The bearing I8 is secured by bolts through the bolt holes 24 and this bearing includes a bearing cap 26 which is fastened to the top channel 22 of the beam by bolts 26' which pass through the openings 26 in said channel. A bearing step TI is secured to the lower channel in a similar way by bolts 21 which pass through the bolt holes 24 in said lower channel. The bearing 18 is completed by a central collar [8 located and confined between the cap 26 and step 21. This collar has a central well 28 which receives a pivot stud 29 depending from the. cap. A stud 30 With the hook-01f device disen- U depends from the collar into a well 3| in the step. The studs are hollow and the wells co-acting therewith will hold ample quantities of lubricant. Any suitable means for supplying lubricant to the wells may be employed.

As is clearly shown in Figure 1, the bolt holes 24 are spaced substantially throughout the length of the channel bars 22 and 23. Thus, by removing the bolts 26 and 21, the bearing [8 may .be moved longitudinally of the channel bars. Thus, its position with relation to the pivot point of the beam which is the post I! may be varied. The additional spaced bolt holes 24 permit the bearing to be fastened in the beam in anyposition therealong. When the position of the bearing l8 which is connected with the pumpingv pow-'- er I0 is varied along the length of said beam, it will be obvious that the swing of the beam will be varied, whereby the movement or stroke of the rod line 2! will be varied. Therefore, by properly adjusting the bearing l8 within the beam, the desired 'length of stroke of the rod'line may be had.

The bearing [9 to which the rod line 2'! is attached includes a cap 82 which is secured to the upper channel 22 by bolts 33 which extend through the bolt holes A step 34 is fastened to the lower channel 23 by bolts 35 which pass through the bolt holes 25 in this lower channel. A bearing collar i9 is located-between the cap and step and is confined therein by a hollow stud 31 which depends from the cap132 into the central Well 38 of the collar. The collar has a depending hollow stud 39 depending into the well 40 of the step 34; A rod Mbywhich connection may be made withthe bearing: l9 extends transversely through the collar 19. Thus, it is seen that the bearings l8 and I9 are similar inconstruction.

The'bearing collars l8 and. i9 have flanged bearing contacts with their caps.and steps,-which contacts may be suitably packed whereby escape of the lubricant from the wells of the bearings is reduced to a minimum. The bearing contacts are large and the oil baths make for adequate lubrication and cool journals. Further, it is noted that the packing at the contacts not only prevents escape of lubricant but also makes the bearings substantially dust and water proof.

For sup'portingthe inner end'of the beam l6 on the post I! so that said beam may undergo a swinging movement, a bearing member isprovided. This member includes abearing step 43 fastenedto the post by U-bolts 44 (Figure 3). A hub 45-is journaled betweenthe step 43 and a cap 46 whichis held on the post by U-boltsll. The hub is formed with brackets 48 which extend contiguous to the channels 22 and 23 of the beam, being secured to said channels by bolts 49. This bearing member is of the oil bath type and is similar to the bearings land IS. The step has a well d3 which receives a hollow stud M depending from the hub. The upper end of. the step fits in the bottom of the hub around the stud. The upper end of thehub engageszin the bottom of'the cap 46 around a stud 46' which depends into a well 45' in the hub. The jointsmay be suitably packed and lubricating oil maybe constantly fed to the wells 45 and d3. 'Ihebearing members are large and adequate to. support the beam.

From the above, it will be. seen that a most rigid swing beam is had. All bearings are provided with an oil bath and are substantiallywater and dust proof.- Because of thebearing adjustment on the beam l6, whereby the bearing I 8 may be shifted to amplify or reduce the swing of said beam and the travel of the connecting rod and the rod line which is coupled thereto, a number of operations may be carried out. When the standing valves become clogged with sand, the stroke can be lengthened to. strike the valves together and jar loose the sand, or the top of a corroded working barrel may be cleaned by changing the stroke. The swing may be worked at an angle and more than one well can be operated thereby. Because of the easy swing a smaller rod line may be employed. Two wells may be pumped by the same swing, one with a long stroke and the other with a short stroke. The beam l6 may be mounted high above the ground or close to it, as the case may be.

When the pumping is to be stopped, the operator merely has to wait until the beam swings to the right (Figure 1) to complete its pull stroke, and then uncoupletherod line 2 by disengaging the hook-oif. device 201 The beamv I6 may continue to swing; however, where the hook I5 is used, the pitmanrwillpushits loop 14 out of said hook, thus riding on-the shelf l3' and. save the swingfrom unnecessary wear.

While the connection to the pitman l l is shown by meansof the hook I5 and loop' I l, whereby the parts are automatically disconnected it is to be understood that any desirable connection between the pitman and bearing I8 may be made, and the automatic disconnecting feature may be eliminated;

It is pointed out that because of the. proximity of the-swing beam iii to the pumping power ID, the amplitude'of swing ofsaid. beam is not as great,.for a given rod line stroke, as Where the swingbeam (usually vertical) is located at a considerable' distance from the pumping power, which is thepresent oil' fieldpractice. By shortening the arc of the beam travel, lateral movement or side play in the post H is greatly reduced. This not only cuts down vibration and side whip, butreduces wear of the parts and makes" for an 1 easy operation.

In Figures '7 and 8, another means for adjusting the'collar bearing 18 is shown. The cap 26' is arranged to slide longitudinally of the beam IE on one side of a-track 50; while the step 21 is mounted to slide on one side of a track 5|. A bottom worm screw 52 is journaled in hangers 53 and threaded through an ear 54 onthe adjacent side of the step 21. This screw has its head projecting from the outer end of the'beam'. By turning the screw 52 the co1lar'l8-is adjusted longi- 1 tudinally of the beam. Any other form of adjustment may be used.
